cc/gcc: update ptachsets for gcc-4.4.{0,1,2}

As reported by Joachim Nilsson <jocke@vmlinux.org>
in: http://sourceware.org/ml/crossgcc/2010-01/msg00005.html

It seems I need to add the 4.3.4/290-index_macro.patch to the GCC 4.4.x
series as well. I immediately trigger the following libstdc++ bug for
4.4.2 with a uClibc .config which has UCLIBC_SUSV3_LEGACY_MACROS set[1].

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
thomas@1461
     6
you have to actually list out the multilibs you want or you will end up with
thomas@1461
     7
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
thomas@1461
    10
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
thomas@1461
    13
of these multilibs by default is negligible.
